Abstract

This study was to analyze data of climate change impacts on social infrastructure using text-mining methodology, and to visualize the spatial information by integrating those with regional data layers. First of all, the study identified that the following social infrastructure; power, oil and resource management, transport and urban, environment, and water supply infrastructures, were affected by five kinds of climate factors (heat wave, cold wave, heavy rain, heavy snow, strong wind). Climate change impacts on social infrastructure were then analyzed and visualized by regions. The analysis resulted that transport and urban infrastructures among all kinds of infrastructure were highly impacted by climate change, and the most severe factors of the climate impacts on social infrastructure were heavy rain and heavy snow. In addition, it found out that social infrastructure located in Seoul and Gangwon-do region were relatively largely affected by climate change. This study has significance that atypical data in media was used to analyze climate change impacts on social infrastructure and the results were translated into spatial information data to analyze and visualize the climate change impacts by regions.

본 연구는 텍스트마이닝 기법을 사용하여 사회기반시설에 대한 기후변화 영향 데이터들을 추출 및 분석하고, 이들을 행정구역 공간정보와 연계하여 분석 표출하고자 하였다. 우선 전력시설, 교통 도시기반시설, 유류 자원관리시설, 환경시설, 용수공급시설의 사회기반시설 중 다섯 가지(폭염, 한파, 호우, 대설, 강풍) 기후 요소로부터 영향을 많이 받은 시설을 파악하고, 각 시설별로 주요한 영향을 미치는 기후 요소를 분석하였다. 사회기반시설의 기후변화 영향은 시설의 위치에 영향을 받을 것으로 기대되어, 사회기반시설 기후변화 영향을 지역 중심으로 비교 분석 및 시각화 하였다. 연구 결과, 사회기반시설 중 교통 도시기반시설이 기후변화 영향을 가장 많이 받았으며, 사회기반시설에 대한 기후변화 영향은 주로 호우와 대설에 의해 발생하는 것으로 확인되었다. 사회기반시설 기후변화 영향의 공간정보를 분석 및 표출한 결과, 강원도와 서울 지역에 위치한 사회기반시설들이 기후변화 영향을 상대적으로 많이 받은 것으로 나타났다. 본 연구는 텍스트마이닝을 통해 사회기반시설 기후변화 영향에 대한 비정형화된 정보를 추출 및 처리하여 분석하고, 이를 공간정보로 표출 시도하였다는 점에서 의미가 있다.
